An information processing apparatus includes a receiving unit and a determining unit. The receiving unit receives read information that is read by a reading unit from a storage medium a plurality of number of times. The determining unit determines abnormality in a reading process performed by the reading unit, based on a first result acquired by comparing a time interval of reading the read information with a first threshold, or on a second result acquired by comparing the number of times the reading is performed with a second threshold.
Legal claims defining the scope of protection, as filed with the USPTO.
1. An information processing apparatus comprising: a receiving unit configured to receive read information that is read by a reading unit from a storage medium a plurality of number of times; a determining unit configured to determine that there is abnormality in a reading process performed by the reading unit when the number of times the reading is performed is less than a threshold, and a detecting unit configured to detect a moving speed of the storage medium moving relatively to the reading unit, wherein the determining unit is configured to calculate a prediction of the number of times information to be read is read as the threshold, based on the moving speed, and on a readable range of the storage medium.
2. The information processing apparatus according to claim 1 , further comprising the reading unit.
3. The information processing apparatus according to claim 2 , wherein the information processing apparatus is provided to a moving body configured to move relatively to the storage medium.
4. An information processing method comprising: receiving read information that is read by a reading unit from a storage medium a plurality of number of times; detecting a moving speed of the storage medium moving relatively to the reading unit; and calculating a prediction of the number of times information to be read is read as a threshold, based on the moving speed, and on a readable range of the storage medium; and determining that there is abnormality in a reading process performed by the reading unit when the number of times the reading is performed is less than the threshold.
5. A computer program product having a non-transitory computer readable medium including programmed instructions, wherein the instructions, when executed by a computer, cause the computer to perform: receiving read information that is read by a reading unit from a storage medium a plurality of number of times; detecting a moving speed of the storage medium moving relatively to the reading unit; calculating a prediction of the number of times information to be read is read as a threshold, based on the moving speed, and on a readable range of the storage medium; and determining that there is abnormality in a reading process performed by the reading unit when the number of times the reading is performed is less than the threshold.
